METHOD OF SYNTHESIS OF TRANS-1,2-DI-(SUBSTITUTED)-CYCLOBUTANES Russian patent published in 1998 - IPC

Abstract RU 2109719 C1

FIELD: organic chemistry and technology. SUBSTANCE: trans-1,2-di-(substituted)-cyclobutanes are synthesized by interaction of 1-octene, allylbenzene or 4-vinylcyclohex-1-ene with dialkylaluminium chloride of the formula R12

AlCl where R′ - Et, i-Bu and metallic sodium in the presence of zirconium-containing catalyst (ZrCl4) in argon atmosphere at the room temperature in tetrahydrofuran medium followed by its distilling off. Reaction mass is cooled to -5 C by successive addition of ether, catalyst containing palladium acetylacetonate and triphenylphosphine and allyl chloride at three-fold excess with respect to aluminoorganic compound and stirring at the room temperature for 6-10 h. Synthesized compound is used for synthesis of antiviral drugs, pesticides and low-molecular bioregulators. EFFECT: improved method of synthesis. 1 tbl
